Departed Sans Souci wharf (just west of Rocky Point Road) at 8am in unexpectedly good conditions. Briiefing was comprehensive, and the boar anchor was right above the cave where a couple of grey nurse sharks hang out, so there they were as advertised. Visibility wasn't great but managed to capture a few atmospheric video clips. When we'd seen enough of the sharks (and probably to their relief) we headed left round the end of the reef, where a wobbegong was lying on a ledge. Then back to where the anchor had been, only to find it wasn't there any more. This meant a free ascent, a midwater stop and a fair snorkel back to the boat.

Fourth Element dry suit, Oceanic Chute 2, 12 litre tank. 29lbs
